1 June 2023. Val d’Arda, N. Apennines, Italy. When in the area I reliably find chrysidids at this location, a south-facing rocky and herb-covered trackside bank. Four species are regular but this one was new to me. It has a blue T3 with four low points. Is it possible to identify from these photos? As usual I don’t have an image of the sternites. I would be grateful for any advice! Thank you.
